Thank you for the so important comment.

Unfortunately, the end-of-therapy fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) image was not obtained after proper protocol to inhibit the physiologic uptake of the myocardium, as the patient was mistakenly considered as routine oncology case. From the fact that the interim FDG PET/CT was negative and that the mediastinal FDG uptake was resolved, we considered the remnant uptake of the heart on end-of-therapy FDG PET/CT to be physiologic. We regret that we did not prepare the patient with the cardiac protocol of low carbohydrate diet and longer fasting time. Subsequent follow-up studies over a year and half have demonstrated no evidence of tumor recurrence.

But the patient has been completely in normal life, and transthoracic echocardiogram, and electrocardiogram (ECG), 24 hours ECG monitoring showed the same as for 3–4 year. If we have another chance to check up FDG PET/CT, then we will do cardiac preparation.
